Release of extracellular products by phytoplankton with special emphasis on polysaccharides
Organic substances are released from phytoplankton cells during all phases of growth. Carbohydrates, especially polysaccharides, sometimes comprise 80–90% of the total extracellular release. NutrientExpand

Production of carbohydrates by marine planktonic diatoms. I. Comparison of nine different species in culture
Abstract Nine different species of marine diatoms, all but one isolated from the Trondheimsfjord, were grown under the same chemical and physical conditions in dilution/batch culture. One species wasExpand

The effect of pH on growth rate, biochemical composition and extracellular carbohydrate production of the marine diatom Skeletonema costatum
The marine diatom Skeletonema costatum was grown at different pH values in a semicontinuous cultivation system which kept the pH at a pre-set value. Growth rate was nearly constant at pH 6·5–8·5Expand

A sensitive and rapid method for analysis of dissolved mono- and polysaccharides in seawater
A spectrophotometric method is described for the determination of dissolved mono- and polysaccharides in seawater. It is based upon the well known alkaline ferricyanide reaction, but uses the reagentExpand

Production of carbohydrates by the marine diatom Chaetoceros affinis var. willei (Gran) Hustedt. I. Effect of the concentration of nutrients in the culture medium
Abstract The chemical composition of cells of Chaetoceros affinis var. willei (Gran) Hustedt grown in batch culture was markedly influenced by the concentration of nutrients in the medium. In theExpand

Studies on the phytoplankton ecology of the Trondheimsfjord. I. The chemical composition of phytoplankton populations
Abstract Samples of phytoplankton populations from the Trondheimsfjord, collected in 1970 and the first five months of 1971, have been analysed for carbohydrate, protein, lipid, and phosphorus. LipidExpand

Studies on the phytoplankton ecology of the trondheimsfjord. III. Dynamics of phytoplankton blooms in relation to environmental factors, bioassay experiments and parameters for the physiological
Abstract Quantitative phytoplankton sampling was carried out at weekly intervals at one station in the central part of the Trondheimsfjord and at irregular intervals at one station near TrondheimExpand

Monthly profiles of DOC, mono- and polysaccharides at two locations in the Trondheimsfjord (Norway) during two years
Abstract Profiles of water samples were collected monthly during 2 years at two locations from the Trondheimsfjord on the Norwegian coast. Concentrations of dissolved organic carbon (DOC) wereExpand
